How does DKIM record work?
Every day, spam is more present, annoying, and dangerous! It’s not only about an undesired bunch of messages taking your inbox space. Nowadays, opening the wrong message and clicking its images or downloading its files could be like opening Pandora’s box! Phishing attacks, malware, and all sorts of scams could be attached to it.
What is the DKIM record?
DKIM record or DomainKeys identified mail is a security standard for domains to sign outgoing e-mails through cryptographic authentication. This way, domains can demonstrate the e-mails sent from their side are legit. Therefore they can be trusted. Besides, the DKIM record secures messages to avoid being altered while they are in transit (sending server-recipient server).

What is an SPF record and How Does it Work?
E-mailing is not new, but it keeps being a widely-used communication form. It’s the official way companies use to approach clients, employees, providers, etc.
Cybercriminals know it, so they try all sorts of malicious tricks to get into your communications. Spoofing here and there, they can send e-mails on companies or people’s behalf just to use their reputation and trustability to cheat others.
That’s why the SPF (sender policy framework) protocol emerged for making e-mailing a safer game.
You (administrator) have the way to limit who can send messages from the domain, and the recipient can check such authorization to decide and take proper actions. It sounds already less risky, don’t you think so?

Verifying your domain with a TXT record
Before we start the topic of the TXT records, we are just going to scratch the surface of the DNS (Domain Name System). First, we will learn what DNS is, a DNS record, and the TXT record. That way, you can better understand the process of the verification of your domain.
What is DNS?
DNS is the universal translater that links domain names to their IP addresses. It is used on all websites and many services like, for example, web hosting and emails. You should know that DNS works with DNS records, which are instruction sets, linking various resources (names, IP addresses, services, etc.) together.
